3 Claims. (Cl. 281-34) The present invention relates to the manufacture of book covers or temporary bindings for books.

At the present time, the paper-backed or pocket book is becoming more and more popular and publishers are printing not only current fiction in this manner but also famous works, technical books and the like which the buyer will tend to retain and possibly place with his standard bound books.

Unfortunately, while the printing and plates of these paper-backed books are usually of excellent quality, the covers in many cases do not lend themselves to installation in a permanent book collection, both from the point of appearance and resistance to handling.

The present invention recognizes this problem and aims to provide an adjustable book cover assembly or ternporary binding that is adapted to be quickly and easily mounted on a standard paper-backed book and which will give a book of this nature an appearance and quality equal to those of a standard bound volume.

Accordingly, the invention comprises an adjustable book coverassembly adapted for use in the binding of paper-backed books which consists of an outer cover of suitable exible material which can be adjusted to suit books of varying thicknesses and an inner ap cover which provides additional reinforcement and a means of placing a title on the exterior of the cover. More specifically, the outer cover is of substantially rectangular outline and is made preferably of a single piece of material folded on itself at each side to provide opposed inwardly facing pockets or flaps adapted to receive at least a por tion of the top and bottom covers of the book to Ibe bound. The central portion of this outer cover is provided with a pair of transverse spaced apart indentations or perforations of a lengtn suihcient to span the width of the thickest pocket book and these indentations are adapted, when pressure is applied, to open and provide narrow slits.

The inner flap cover is also preferably a single piece of material, for example a piece of paperboard or cardboard, which is of a size adapted to t within the outer cover with the side marginal portions fitting snugly within the outer cover side flaps. This inner cover is provided with indicating lines adapted to provide a reference for the location of the book to be bound, and an upper central portion so marked is adapted to be slit inwardly to provide a tongue portion adapted to receive the title of the book on the surface against the outer cover. When the cover is assembled this tongue portion of the inner cover is inserted through the slits in the outer cover so that the portion bearing the title is exposed.

Having thus generally described the nature of the invention, particular reference will be made to the accompanying drawing illustrating a preferred embodiment thereof, and in which:

Figure 6 is a sectional view of the construction shown in Figure l along the line 6-6.

Figure 7 is a sectional view of the construction shown in Figure l along the line 7-7.

`Figure S is a'sectional view of the construction shown in Figure l along the line 8 8. Y

With particular reference to Figure 2 of the drawings, a preferred construction of a book cover assembly in accordance with the invention consists of the combination of an outer cover 10 and an inner flap or cover 12 which are mounted over the usual covers A aand B of a standard paper-backed or soft bound book, as shown in Figure 1.

The outer cover 10, which is preferably made of a exible plastic material, is preferably formed from a onepiece blank, as shown in Figure 3. The outer side marginal portions 14, 16 are folded over and secured along the top and bottom margins, for example by known heat sealing processes, to provide inwardly facing side flaps 18, 20.

Prior to the folding of the ilaps 18, 20 and preferably during the production cutting of the blank, the marginal portion 14 is slit, as indicated at 15, providing the portion 17 which, when the side iiaps are connected, provides an integral vbook mark. At the same time the central portion of the blank is embossed or partially perforated to define the break-out slits 30a, 30b. Prefer ably, these slits are defined by the embossing or perforating so that they can be readily opened out when the cover is utilized but remain closed to avoid catching or deformation when the covers are handled or packed for shipping prior to their use.

The inner flap or cover 12 is also made of a one-piece blank of material, preferably of a less flexible nature than the outer cover, for example paperboard or cardboard, and is provided on one surface with indicating lines or perforations 13a, 13b, dening an area 15 corresponding in location to the spacing between the slits 30a, 30b on `the outer cover iii. The center line of the inner lap 12 is also indicated by a suitable line or lines 31 to provide a means of accurately locating the book to be bound.

To assemble the cover of the invention, the book to be bound, for example as indicated at C in broken lines in Figure 2, is placed over the inner ap 12 with the center of its spine on the line 31. A line is then drawn or scored along both sides of the book from top to bottom to indicate the width on the inner ap 12. The title, author, or any other desired identifying mark is then written or typed on the area 15 of the ap 12. The flap 12 is then cut along a pair of lines or perforations 32 down to the bottom line 13b defining the area 15 and inwardly at each side along the line 13b to the mark delineating the width of the book. The inner ap 12 is then turned over and the edges of the portion 19 defined by the newly cut slots folded inwards along the drawn lines, as shown in Figure 5.

The transverse slits 30a, 30h are opened up and the inner ap 12 placed on top of the cover 10 with the portion 19 inserted into the slit 30b up and back through the top slit 30a, as shown in Figure 6. The side portions of the inner ap 12 are then placed in the side aps 18, 20 of the outer cover pushing the inner ap well up to the top of the cover 10. The book C is then placed on top Patented May 3, 1960 of theinner ap 12 and the top and bottom covers in-A serted in the cover side flaps 1S and 20, 'as shown in section in Figure 8. The end result is a permanently bound attractivebook with aneat title card we ll suited for insertion in a library or the like.Y A
